The pin becomes easier as you use the weapon and clean it.......if it slides grease it(rails) ......if it rolls oil it......these things love to be shot and seem to improve with use, as to the mag, the brand most used for Sig is usually MecGar made in Italy excellent quality and spring may be a bit strong but they feed and are solid reliable......JJ

I love my Exeter sp2022 and can say the slide lock pin loosens over time (lubricate the ends that go in the gun and field strip several times). Also to loosen up the magazine spring, fully load the mags and let them sit for a few weeks
